Surface Finishing
Surface finishing is the process of artificially forming a surface layer on the surface of a product with different mechanical, physical and chemical properties of the substrate. The purpose is to meet the enhanced performance, corrosion resistance, appearance decoration or other special functional requirements of the product.
We can provide most of the surface finishing processes on the market, such as electroplating, oxidation, sandblasting, polishing, surface hardening, sanding, knurling, laser engraving, passivation, pickling and more. Surface treatment is a key step in the metal parts manufacturing process, and we use the best processes to produce the most demanding products to meet product quality and application requirements.

As-machined |
The standard finish for our parts, the “as machined” finish, has a surface roughness of 3.2 μm (126 μin), which removes sharp edges and deburs parts cleanly. |

Sand Blasting |
Sand blasting is the process of powerfully propelling, generally with high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities. |

Anodizing |
Keeping our parts in the long term, our anodizing process resists corrosion and wear. It’s also an ideal surface treatment for painting and priming, and it looks great too. |

Electroplating |
Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations. |

|
Polishing |
Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements. |

Powder Coating |
Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm. |

Painting |
Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic. |

Black Oxide |
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance. |

Alodine |
Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts. |
